Be it knownthat I, JOHN B. MOOUTCHEON, a citizen of the United States,residing at Battle Creek, in the county of Calhoun and State ofMichigamhave invented newand useful Improvements in Attachments forPneumatic Stackers, of whichthe following is a specification. j

' This invention relates to attachments to pneumatic stackers used inconnection with threshing-machines. In a pneumatic stacker orwind-stacker, as more commonly called, the strong draft caused by theblast of air is liable to carry off more or less grain with the straw;and itis the object of my invention to avoid this waste or loss of grainand convey it to a suitable receiver.

My invention consists in features of construction and novel combinationsof parts in a wind-stacker attachment for threshing-machines, ashereinafter described and claimed.

In the annexed drawings, illustrating the invention, Figure 1 is avertical longitudinal section of my improved wind-stacker attachment.Fig. 2 is a vertical cross-section of the same.

Referring to the drawings, the numeral 1 designates what maybetermed'the inner tube or section of a telescopic chute 2, whichcomprises also an outer tube or section 3, the one tube being arrangedto have a sliding adjustment with relation to the other. On theinnermost end of the tube 1 is a collare and in one end of the tube 8 isa collar 5, the said collars 4 and 5 being so disposed as to center thetube`1 in the tube 3 and permit sliding adjustment of the said tubes ortelescopic sections without great friction, and these collars 4 and 5also serve as stops to prevent disconnection of the telescopic tubeswhen drawn out to full extent. Ata suitable point on the tube 1 is acollar 6, which serves as a stop to limit inward or shortened adjustmentof the telescopic tubes. The outer end of the tube 1 is curved downwardand has attached theretoan adjustable curved elbow 7, which constitutesthe inlet to the telescopic chute and is to be placed insuch proximityto the threshing-machine as to receive the straw that is carried oft bythe airblast. To permit adjustment of the elbow 7, connection 8 with theit may have a hinged 189e. serial no. 684,759. dromen.)

lower end of a yoke 9, that is secured to the tube 1 of the telescopicchute.l In the upper end of the yoke 9, above the tube 1, is journaled apulley 10, to which is attached one end of a rope or fiexible connection11, which is passed over a guide-roller 12 and secured at its outer endto a lug .1 3 on the farther end of the telescopic tube 3. Theguideroller V12 maybe supported above the yoke 9, as shown. By rotatingthe pulley 10,to which a winch-handle may be connected, the rope 11 willbe wound on said pulley and thereby draw together the tubes 1"and'3, soas to shorten the telescopic chute. The outer end ofthe tube 3 is openat its under side to form an outlet 14 for discharge of straw. y Toguard this outlet, there is secured to the end of the tube 3adownwardly-curved hood 15, that is provided with an adjustable section16, which is hinged at 17, as shown.

In most pneumatic stackers considerable grain is carried oif with thestraw and can.` not be readily recovered. 'For the purpose of avoidingthis waste of grain I have provided meansy for separating the straw fromsuch grain as may be carried with itinto the straw-chute and to conductVthe saved grain to a suitable receptacle. As a means for accomplishingthis result there is hinged at 18 in one end of the straw-outlet 14 aseries of fingers 19, that extend across the somewhat funnel-shapedinlet end 20 of an adjustable grain-spout 21,which is hinged or pivotedat the same point'as saidfingers. The spout 21 is extended backwardbeneath the telescopic chute 2, and it is adjustably supported at ornear its rear end by means of sliding connections 22 and 23, which mayconsist ofbars or rods connected by a set-screw 24C or otherwise, theupper bar being arranged to have a`pivotal connection 25 with the underside of the main or outer chute-section. The rear-V end of the spout 21is curved downward to for-m a grain-outlet 2G, through which the grainwill be discharged into any suitable receptacle.

In passing out from the chute the straw is deiiected upward toward thetop of the tube 3 by means ofthe fingers 19, while any grain i that mayhave been carried out to that point will fall between 'the said iingersinto 4the inlet end of the grain-spout 21 and be there-` by conducted toa suitable receiver. This ICO the same point as the adjustablegrain-spout and extended across the inlet to the said spout,substantially as described.

2. In a pneumatic stacker for threshingmachines, the combination of atelescopic straw-chute having an outlet in the under side of its outerend, an adjustable grainspout having its inlet end in communication withthe chute-outlet and hinged thereto, a series of fingers hinged at thesame point as the grain-spout and extended across its inlet, andadjustable connections between the rear portions of the straw-chute andsaid grainspout, substantially as described.

In testimony whereof I have hereunto set my hand in presence of twosubscribing Witnesses.

JOHN B. MCGUTCHEON.
